This is our highest capacity battery. It is dimensionally the same as the VPH900. You can have it all, a lightweight battery, but still be able to park your car for long periods and power all your electronics! This battery is recommended if you want the highest capacity and/or the most starting power. It is also recommended for high-end cars that may have larger, heavier starting batteries for larger engines or more electronics, or both (Mercedes AMG, Ferrari, etc).
